Introduction to Transient and Steady-State Responses
A stable system settles. An unstable system has increasing amplitude in its fluctuations.
The steady-state error is how accurate a system will be once settled.
If we subject control systems to standard input we can compare and tune their performance.
Consider three inputs:
i. step input ii. ramp input (linear change with time) iii. harmonic input (considered in vibration)
These inputs are useful because they
- are easily to apply in practice
- approximate to operating conditions in control systems
Practical Measurement of Transient Response
a. maximum overshoot b. number of oscillations c. rise time d. settling time e. steady state error
